Anna007 [38]
 <span>DNA contains the code for all an organism's protein. Since many of the organism's structures, processes, and growth depend on protein the DNA is central to the well being of all organisms. In eukaryotes, the DNA is locked up in the nucleus. The area of the cell where proteins are made is in the cytosol (ribosomes). In order for the protein to be made the DNA has to produce a copy of the blueprint m-RNA. This messenger RNA will take the code to the ribosome. The process by which m-RNA is made is called transcription. A-U, C-G base pairing rules. Once on the ribosome another RNA comes into play t-RNA. This is called transfer RNA. Here it will take an amino acid and place it in the correct order to produce the desired protein. This is called translation. It begins with a start co don AUG. and ends with a stop codon. The protein will then go to the Golgi apparatus and be formed into its final shape.

denis-greek [22]

People with central sleep apnea experience a complete cessation of respiratory activity for brief periods of time yet do not have frequent awakenings and do not tend to feel tired during the day.

<h3>What is sleep apnea?</h3>

Breathing regularly stops and starts during sleep, which is known as sleep apnea. People may have sleep apnea if they snore loudly and still feel exhausted after a full night's sleep.

These are the primary forms of sleep apnea:

The more prevalent type of obstructive sleep apnea happens when throat muscles relax.

Central sleep apnea, which develops when your brain fails to properly activate the breathing muscles,

When a person has both central and obstructive sleep apnea, it is known as complex sleep apnea syndrome, also called treatment-emergent sleep apnea.

In a short essay (100-150 words), describe Darwin's view of how natural selection resulted in
Zinaida [17]

Answer:

Charles Darwin was the man who came with the theory of natural selection. He witnessed finches within the Galapagos Islands and made notes on the similarities and differences of the finches across the group of islands. Each of the islands comprises finches, which were identical, however distinct in different ways.  

Darwin found that the finches appeared to vary on the basis of the food sources available on each of the islands. If the prime food were seeds, the finches seemed to possess thicker beaks in order to break the seeds so that they can consume them.  

On the other hand, if the prime food sources were insects, then the finches seemed to exhibit smaller and pointer beaks so that they could hold the insects readily. In this way, there is unity in diversity. All of these birds are finches and exhibited a common ancestor from which they have originated into the distinct species as mentioned.  

Their variations lie in the habitats, in which they now inhabit. They had to amend with their environments in order to thrive, thus, offering diversity to unity.
